Special Land Use Category Projects and Other Development and Redevelopment Projects, as defined by provision C.3 of the MRP, are required to complete the Stormwater Requirements Checklist Form. This form will assist both the project applicant and City staff through the planning/permitting process and will help identify the pertinent stormwater requirements.
